It's very easy here is an example
19
X3
___
Nine times three is 27 so
19
X 3
____
7
You just leave the seven there then
2
19
X 3
_____
7
You put the two on top of the one.
After that you multiply 1x3=3 then the two on top of the one adds to 3 + 2
Hope this helps the answer is 619.75 or if you round 620
Good luck!

Im not exactly sure but I think you multiply to get the answer
Answer:
x = ± 
Step-by-step explanation:
3x² - 9 = 0 ( add 9 to both sides )
3x² = 9 ( divide both sides by 3 )
x² = 3 ( take square root of both sides )
x = ±
or
3x² - 9 = 0 ← factor out 3 from each term
3(x² - 3) = 0
equate x² - 3 to zero and solve for x
x² - 3 = 0 ( add 3 to both sides )
x² = 3 ( take square root of both sides )
x = ±
Answer:
x = 1
y = -3/2
Step-by-step explanation:
Step 1: Arrange the equations with like terms in column.
Step 2: You want 1 set of coefficients that are opposites. This problem already has opposites: -2y and +2y.
Step 3: Solve for x.
4x-2y=7
3x+2y=0
--------------
7x = 7
x = 1
Step 4: Substitute the value of x and solve for y.
4(1)-2y=7
4-2y=7
-2y=7-4
-2y=3
y=-3/2
